If a truck with air suspension is experiencing shock breakage, which is NOT a necessary check?

In the context of air suspension systems, checking tire pressures is not directly related to the issue of shock breakage. While maintaining correct tire pressure is crucial for overall vehicle safety and performance, it does not directly impact the functionality of the air suspension system or the specific shocks that may have broken.

The part numbers of the shocks are relevant because ensuring the correct parts are installed is essential for maintaining proper suspension dynamics. Verifying the function of the ride height control valve is critical since this component regulates the air pressure in the suspension system to maintain ride height and stability. Checking the torque of the shock mounting bolts is also important, as loose or improperly torqued bolts can contribute to shock failure.

Therefore, while checking tire pressures is important for vehicle safety, it does not specifically address the problem of shock breakage in an air suspension system, making it unnecessary in this context.
